When designing products for maximum antiaging benefits, formulators should consider both intrinsic and extrinsic aging factors—intrinsic being naturally programmed aging, and extrinsic resulting from accumulated damage. This article describes a combined approach to reduce the signs of aging, the first of which focuses on intrinsic aging by slowing cell proliferation rate to preserve cells in their younger stage. The second approach aims at extrinsic factors to protect the skin from photo- and oxi- dative damage.
